Modifying the Device Tables

Each of the three tables shown above are are limited in effect by

a byte value. The I/O CONSOLE TABLE has a total of thirteen

entries, but only as many entries as there are PHYSICAL CONSOLES

(as designated by the constant at location 0C10) will be read in

by the system at boot time. The LIST DEVICE TABLE has a total of

five entries, but only as many entries as there are LIST DEVICES

(as designated by the constant at location 0C13) will be read in

by the system at boot time. The AUX DEVICE TABLE has a total of

four entries, but only as many entries as there are AUX DEVICES

(as designated by the constant at location 0C58) will be read in

at boot time.

Each of the entries in these tables contain hex values

corresponding to USARTs assigned to the that entry's device. The

USART numbers are mapped to the actual physical I/O boards in the

manner illustrated in TABLE # 1.
